Hello Team,

Job Configurations details:

conf = { "app_name": "CX360", "spark.yarn.queue": "CXMT",

            "spark.port.maxRetries": 500,

            "spark.driver.memoryOverhead": 4096,

            "spark.executor.memoryOverhead": '14g',

            "spark.driver.memory": "50g",

            "spark.driver.maxResultSize": 0,

            "spark.executor.memory": "50g",

            "spark.executor.instances": 2,

            "spark.executor.cores": 5,

            "spark.driver.cores": 5

}

Tried with different values but still facing issues, please find yarn queue capacity details

Queue Name : CXMT
Queue State : running
Scheduling Info : Capacity: 8.0, MaximumCapacity: 8.0, CurrentCapacity: 0.8620696

Please do the  needfull ASAP.

Hi,

Is this is only the spark job failing with OOM error? what was the initial executor and driver memory that you have tried with?

Can you also try to into increase the num-executors and executor-cores and run the job? rerun the job by increasing executors and cores and see if it works.
